Description
Technical field
The utility model belongs to physical teaching aid field, in particular for the teaching aid field of Conversion of Energy.
Background technology
The teaching aid of existing Conversion of Energy is very abundant, but, still there is the experiment being not easy to demonstrate and study.The problem of Conversion of Energy whether is had in the process that such as ammeter pointer rotates, for another example, can the problem of reometer Conversion of Energy be linked together with wind energy? these problems are all the problems being worth solving.
Utility model content
In order to make up the deficiency of existing teaching aid, the utility model proposes a kind of teaching aid of Conversion of Energy, the utility model is such: for demonstrating the teaching aid of Conversion of Energy, comprise base, the vertical panel be fixedly connected with base, first reometer, second reometer, it is characterized in that: panel is installed with the first reometer, panel is installed with the second reometer, the positive terminal of the first reometer and the positive terminal of the second reometer are for being electrically connected, the negative terminal of the first reometer and the negative terminal of the second reometer are for being electrically connected, and, second reometer inwall is fixedly connected with one for blowing the electric fan of the second ammeter pointer, and the first reometer 1, second reometer 2 is all moving iron instrument.
The utility model can also like this: for demonstrating the teaching aid that wind energy transformation is electric energy, comprise base, the vertical panel be fixedly connected with base, first reometer, second reometer, it is characterized in that: panel is installed with the first reometer, panel is installed with the second reometer, the positive terminal of the first reometer and the positive terminal of the second reometer are for being electrically connected, the negative terminal of the first reometer and the negative terminal of the second reometer are for being electrically connected, and, second reometer inwall is fixedly connected with one for blowing the electric fan of the second ammeter pointer, and the second ammeter pointer be fixedly connected with one for stop electric fan the blinker of wind that blows, the shape of blinker is rectangle, and the first reometer 1, second reometer 2 is all moving iron instrument.
The utility model structure is simple, for teaching, can promote teaching efficiency, be conducive to student and carry out inquiry activity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the partial structurtes schematic diagram of the utility model embodiment two.
In figure: 1-first reometer, 2-second reometer, 3-base, 4-panel, 5-electric fan, 21-second ammeter pointer, 211-blinker.
Embodiment
Embodiment one
See accompanying drawing 1, being structural representation of the present utility model, is front elevation.For demonstrating the teaching aid of Conversion of Energy, comprise base 3, the vertical panel 4 be fixedly connected with base 3, first reometer 1, second reometer 2, it is characterized in that: panel 4 is installed with the first reometer 1, panel 4 is installed with the second reometer 2, the positive terminal of the first reometer 1 and the positive terminal of the second reometer 2 are for being electrically connected, the negative terminal of the first reometer 1 and the negative terminal of the second reometer 2 are for being electrically connected, and, second reometer 2 inwall is fixedly connected with one for blowing the electric fan 5 of the second ammeter pointer 21, and the first reometer 1, second reometer 2 is all moving iron instrument.
Using method: power to electric fan 5, electric fan 5 rotates, and blows the second ammeter pointer 21 and rotates, so the second reometer 21 act as the effect of generator, because there is the second reometer 2 to power, so the first reometer 1 shows the existence of electric current.
Principle: moving iron instrument is that coil is subject to Ampère force effect and rotates, moving iron instrument internal cable circle, magnet.So, can with it as Blast Furnace Top Gas Recovery Turbine Unit (TRT).
What need explanation also has: because meter pointer has certain thickness, so, after wind, be rotary.Various equivalent modifications should be known, and the front of reometer should towards observer.What be electrically connected is meant to: connect with wire.
Further:
Embodiment two
See accompanying drawing 2, be the structural representation of the utility model local, it is intended to show: the second ammeter pointer 21 be fixedly connected with one for stop electric fan the blinker 211 of wind that blows, the shape of blinker 211 is rectangle.
So have: for demonstrating the teaching aid that wind energy transformation is electric energy, comprise base 3, the vertical panel 4 be fixedly connected with base 3, first reometer 1, second reometer 2, it is characterized in that: panel 4 is installed with the first reometer 1, panel 4 is installed with the second reometer 2, the positive terminal of the first reometer 1 and the positive terminal of the second reometer 2 are for being electrically connected, the negative terminal of the first reometer 1 and the negative terminal of the second reometer 2 are for being electrically connected, and, second reometer 2 inwall is fixedly connected with one for blowing the electric fan 5 of the second ammeter pointer 21, and the first reometer 1, second reometer 2 is all moving iron instrument, second ammeter pointer 21 be fixedly connected with one for stop electric fan the blinker 211 of wind that blows, the shape of blinker 211 is rectangle.
The utility model structure is simple, benefits to student's inquiry activity.
